STITCHING FOR SECURING SHANK-EY E BUTTONS AND METHOD OF FORMING THE STITCHING.

Application filed December29, 1913.

To all whom it may concern:

Be it known that I, VVIIJLIAM F. LAUTEN- sm-ILAonu, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Stitching for Securing Shanlcl-Qyc linttons and Methods of Forming the Stitclr ing. of which the following is a specification.

My invention relates primarily to stitch ing for securing shank-eye buttons to shoes and to the method of attaching such buttons to the shoe, and I have shown and described my invention with relation to such use, from which its application to shanlreye buttons in other relations may be readily perceived.

It is one of the objects of my invention to secure shankfeye buttons in place in a novel manner so that the eye of the button is aflixed closely to the surface upon which the same is secured. It is a further object of my invention to provide a novel stitching and method of forming the same whereby the stitching for each button in dependently secures the button in place; further to provide a novel stitching and method of forming the same whereby each button is maintained in place by a knotting in the stitching; further to provide a stitching andmethod of forming the same. for se curing the shank-eye button in place by means of a. single thread so manipulated as to pass a plurality of the stretchesof a loop of the thread through the shank-eye of, the button and through the material at both, sides of the shank-eye; and,rfurther to securethe loop in place below the, surface at which the button is located.

The stitching may be formed manually or by machinery, as may be desired, although in the ordinary course of manufacture the.

stitching?1 will be more generally. accomplished v suitable machinery or combine tions of ev-ices for, acting on the thread. I have not h rein shown any me hanismior manipulating. the: hr ad 1 a compl shi g the desired results, as any mechamismsuib able for the purpose may he employed.

I have, in the drawings, illustrate Val-i 011 stagesin the course of the. formation o the stitching, these stages. being selectiye.

or arbitrary stages. selected atnemts ia he Specification of Letters Patent.

formation of the stitching which will most clearly show the manipulation of the thread, it being understood that, especially when the stitching is formed by machinery, the operations or manipulations preferably take place in a continued and uninterrupted series of steps for forming the stitching.

The invention will be further readily understood from the following description and claims. and from the drawings. in which latter:

Figure l is a perspective view showing a primary loop of the thread received through the material, the latter being shown in ver tical section taken on the line of the stitching and partly broken away, it being as sumcd that a previous button has been attached to the material and the thread to form the stitching led therefrom for forming the stitching to be described.

Fig. 2 is a similar view showing the button with its eye received about the loop.

Fig. is a similar view showing the pri mary loop flexed in the line of feed preparatory to being received reversely through the material.

Fig. 4 is a similar view with the loop received reverselv through the material.

Fig. 5 is a similar view showing a secondary loop received through the primary loop,..with the slack drawn out of the primary loop.

Fig. 6 is asimilar view showing the secondary loop flexed reversely and the pri-' mary loop drawn in a manner sothat a knot is formed between one of the stretches of the secondary loop and the primary loop.

Fig. 7is a bottom view of the same.

Fig. 8 is a perspective view showing the secondary loop passed through the materiali.

the latter being shown in vertical section on the line of the stitching, and partly broken away.

Fig. 9. is a similar view showing the secondary loop imposition .tobe received about the shank-eye of the button.

Fig. 10 is a plan View ofthe same, the

head'of the button being broken away.

Fig. .11. is a perspective viewshowing the secondary loop .drawn taut its an. ply stretch passed. through the primary 00p for torming a. knot therewith.

Fig. 12 is a bottom view of the same.

Fi 13 is an enlarged perspective view showing the stitching in its preferred completed form, the button being broken away at the eyeand the material shown in dotted lines for better illustration of the stitching; and,

Fig. 14 is a plan view showin the completed stitching, the heads of the %uttons being removed, and the coaeting flap with its button-hole being also shown.

While the stitching of my improved method may be accomplished either by manual manipulation or by the operation of mechanical means, it will be assumed for convenience of description, that the stitching is being formed by suitable mechanism in which the material, shown at 11, is fed in the direction of the arrow 0;. This material may be the quarter of a shoe. It will be further assumed that a preceding button or buttons have been attached to the material, and that the stretch 12 of the thread, the latter indicated generally at 13, passes from the stitching of a preceding button to the position at which the stitching for the button being secured in place is located. It will be further understood that the stitching, which I illustrate in the drawings, is formed by a sin le thread which may have its source at a bob in or spool.

At the point where the stitching to be formed is located, the thread is passed through a hole 14, suitably formed in the material either concurrently with or independently of the passing of the thread through the hole, dependin on Whether a thread-needle or hook-need e is employed for the purpose. The thread is received through the hole for forming a primary loop 15, (see Fig. 1).

Theshank-eye '16 of the button 17 is located about the primary loop, (see Fig. 2). This may be accomplished concurrently with the passage of the primary loop through the hole'l or after the primary loop has been received through the hole. The shankeye of the button is arranged crosswise of the stitching, its rounding 18 being arranged to be received under the primary loop and to extend crosswise of the stitching so as to be secured with its shank-eye in line with the button-hole 19 in the coacting flap '20 of the article. (See Fi 14,.) i This coaetin flap may represent t e button-fly of the s oe. The rounding is thereby placed close to the outer surface 21 of the material.

The primary loop '15 is then deflected lengthwise of the p} thof the stitching, (see Fig. 3), which pat 'is indicated by the dotted line 22 in Fig. 10, and is received reverselythrough'the material through a hole 23, (see Fig. 4), spaced fromthe" hole 14 a distance co'rres funding to the length of the stitching, w ich is ordinarily" from three-sixteenths to a quarter of an inch when stitching shoe-buttons. The primary loop may beei the'r pulled or pushed through the hole 23, depending on the instrument employed, if mechanical means or a tool is used for accomplishing the purpose.

By the means so far stated both stretches of the primary loop are received through the material in reverse directions at the re spective sides of the shank-eye of the button and the rounding of the button-eye received under both said stretches. The primary loop is for convenience described as comprisin an initial stretch 24 and a sup ply strete 25.

A secondary loop 26 extends from the primary loop and is received about the buttonshank. For formin this secondary loop I prefer to lead a portion of the supply stretch 27 of the thread through the primary loop, said secondary loop passing through said primary loop from that side of said pri mary loop presented toward the hole 14, which, in the present exemplification, means passing said secondary loop through said primary loop in a direction reverse to the feeding direction a of the material, (see Figs. 4 and 5). The secondary loop is preferably formed in reat part by drawing upon the primary oop for stretching the same across the outer surface of the intermediate portion 28 of the material to which the button is secured, this intermediate portion being located between the holes 14 and 23. The stretching of the primary loop also places the bight 83 thereof at the second hole in thestitching, spaced from the point of the first piercing of the material by the stitching, in order that the knot hereinafter described will be formed proximate to said second hole, so that the walls of said second hole will aid in preventing loosening of the stitch, (see 13).

The secondary loop is flexed in. reverse direction-about the bight 33 of the primary loop, as indicated at 31, (seelFig. 6) and pullin strain referably exerted upon ,the same or stretc ing the stretches of the prinlilary loop and forming a knot 32 between t c this not being preferably formed below the surface 210i the material at the biglit 33 of the primary loop between the primary loop and the in tial stretch 34 of the secondary loop. ,The rounding 18of the shank-eye of the button is thereby firmly pressed against the surface 21; ofthe material. This reverse stretchingof' the secondary loop preferably locate'sthis knot undert'he intermediate portioi128 of the material roximate to the hole 23. A concatenation etween the loops is formed atsai'd knot.

The secondary or supplemental loop is passedi through the material to that side thereof atwhiel*f the button is located, and

rimary loop and the secondaryloop,

messes preferably throu h the hole 14, alongside the stretches 0 the thread theretofiore passed through said hole, (see 8),.as indicated at 36, the bight portioni o the secondary loop being then flexed 'preierabiy lengthwise of the path of the stitching, as shown at 37, and :thezloop spread, as shown at 38, (see Figs. 9 and 16), forbeing received 'aboutthe button and about the button-shank.

A pulling is thereupon exerted upon the supply-stretch 39 of the secondary loop, which is accomplished preferably by pulling upon the supply-stretchof the thread for drawing the secondary loop tightly about the eye-shank of the button, which thereby forms a locking of the stitching, (see Figs. 11 and 12,) and also preferably forms a knot 40 between the supply-end of the supplystretch of the secondary loop and the primary loop adjacent to the knot 32 for securely knotting the parts in place. The pulling taut of the secondary loop also has a tendency to force the shank of the button toward the hole from whiehthesecondary' loop protrudes for wedging the rounding 18 of the shank under that end of the primary loop protruding from said: hole and forcing said rounding toward the material. The supply-stretch of the thread is then passed to the position for the formation of the next stitching for securing the neXt button in place.

The bight 41 of the secondary loop is re ceived above both the initial stretch 2 i and the supply-stretch 25 of the primary loo-p,

(see Figs. 13 and 14:), the stretchesoi thei secondary loop being located preferably at the side of said stretches of the primary loop located above the outer surfaceof the material and atthe edges and slightly under the rounding of the shank-eye of the button. The stretches of the secondary or supplemental loop preferably pass crossingly over the stretches of the primary loop adjacent to the initial hole 14 for forming hitches 42 and 48.

The eye-shank of the button is caused to lie close to the outer face of. the material to which it is attached, with the shank arranged at rightangles to' thei path-of the stitching and in line with the b-uttonahole' 19, shown in the coacting flap 20 of the material, which in a shoe represents the buttonfly, the button on a shoe being attached to the mating edge of the opposite quarter.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is:

l. The method of attaching a shank-eye button to material which consists in passing a loop of thread comprising an initial stretch and a supply stretch through the material, through the shank eye of the button and in reverse direction through the material, at a pointspaced from the point at which said loop is first passed through? the material, passing the supply stretch of the thread through said loop from that side of said loop presented toward the point at which button to material which consists in passing a loop of thread, comprising an initial stretch and a supply stretch, through the material. through the shank-eye of the button and rcversely through the material, at a point spaced from the point at which said loop is first passedthrough the material, passing the supply stretch of the thread through said loop: from that side of said loep: presented toward the point at which said loop is first passed through the material, drawingsai d loop taut for forminga knot proximate to said spaced point, forming a supplemental loop in said supply stretch of said thread, bending said supplemental loop in reverse direction about the bight of said fi-rst named loop, passing said supplemental loop through the material at the beginning prortion of the stitch and about theshankeye' of'the buttomnand" drawing said supplemental loop taut andforming a lsnotatsaidii loop is first passed throughwthcmaterial,

passing the supply stretch of the thread through "said? loop frown that side e f es-id 'lmp' 'fii'esented toward the point at which said loop is first passed through the material for forming a supplemental loop comprising an initial stretch and a supply stretch. pulling upon said last-named initial stretch for drawing said first-named loop taut for forming a knot proximate to said spaced point between said first-named loop and the thread of said supplemental loop, bending said supplemental loop in reverse direction about the bight of said first-named loop, passing said supplemental loop through the material at the beginning portion of the stitching and about the shank-eye of the button, and drawing the supply stretch of the thread taut for forming a second knot at said spaced point between said loops.

5. The method of stitching a shank-eye button to material which consists in passing a loop of thread comprising a pair of stretches through the material and through the shank-cye of the button, passing the sup ply stretch of the thread from the beginning portion of the stitch through the bight portion of said loop from that side of said bight portion presented toward said beginning portion and forming a supplemental loop comprising a pair of stretches, bending said supplemental loop in reverse direction about said bight portion of said firstnamed loop, concatenating said supplemental loop at the end of said stitch spaced from said beginning portion with said firstnamed loop, said loops arranged in concatenated relation downwardly through the material, passing said supplemental loop through the material at the beginning portion of the stitch and about the shank-eye of the button, and pulling upon the supply stretch of the thread for drawing said supplemental loop taut'about said shanleeye, and forming a knot at said end of said stitch between said supply stretch of said supplemental loop and a preceding portion of the stitch.

6. The method of stitching a shank-eye button to material which consists in passing a loop of thread comprising a pair of stretches of thread through the material and through the shank-eye of the button, passing one of the stretches of the thread from the beginning portion of the stitch through the bight portion of said loop from the side of said bight portion presented toward said beginning portion and forming a supplemental loop comprising a pair of stretches, concatenating said supplemental loop at the end of said stitch spaced from said beginning portion with said fiI'SiZ'IlfiIIlBCl loop by bending said supplemental loop in reverse direction about said bight portion of said first-named loop, passing said supplemental loop through the material at the beginning portion of the stitch and about the shank-eye of the button, and pulling upon the supply stretch of the thread for drawing said supplemental loop taut about said shanloeye with its stretches arranged above the stretches of said first-named loop.

In testimony whereof, I have hereunto signed my name in the presence of two subscribing witnesses.
